New lifting based structure for undecimated wavelettransform
Chang‐Soo Lee, Chang Kil Lee, Kyung Yul Yoo · Electronics Letters · 2000
A new structure for the undecimated wavelet transform (UWT) is introduced. This structure combines the stationary wavelet transform with a lifting scheme and its design is based on a polyphase structure. The suggested structure inherits the simplicity of the lifting scheme, such that the inverse transform is easily implemented. The proposed performance of the UWT is verified on a signal denoising application.
